BENJAMIN F. BELLOWS, OF CLEVELAND, OHIO, ASSIGNOR TO ELECTRIC COMPOSITORCOM- PANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

SPACER SELECTING AND IRE-LEASING MECHANISM FOR USE IN JUSTIFYIN G MATRIXOR TYPE LINES.

State of Ohio, have invented a certain new and useful Improvement inSpacer Selecting and Releasing Mechanism for ['se in Justifying Matrixor Type Lines, of wnich the following is a full, clear, and exactdescription.

In the prior patents No. 727,267 and No. 797,549 granted to B. F.Bellows. one of the applicants herein, and also in the. pendingapplication of the said Bellows. Serial No. 330,685, filed August 15,1906. a so-called selecting plate is shown as the means for immediatelyselecting and operating the proper combinations of escapcnients forrecasing the spacers required to justify an assembled line ct matricesor type. This selecting plate, so-called, as shown in said prior patentsand application, is a plate having a plurality of empirically disposedpins projecting from its top surface: and this selecting plate, and thecooperating mechanism shown in either of said patents or in the endingapplication are capable of practical the purpose for which they areintended. The said selecting plate is, however, an expensive piece ofmechanism, and one which may be easily injured and thereby renderedpractically useless.

The primary purpose of the present invention is to irovide a chea i andstrong substitute for t he selecting p ate shmni and described in saidprior patents and application; and also to provide suitable mechanism bywhich saidsubstitute may be caused to operate in the required manner toserve the purpose for which it is designed.

The present invention in the form shown is designed with a specialreference to its employment, in j ustifying mechanism of substantiallythe specific form shown in my said pending application as a substitutefor the spacer selecting and releasing mechanism therein shown. I

The invention consists, broadly, of :1 cylinder carrying a plurality ofproperly placed peripheral projections, and of the combination therewithof suitable means for turning it and moving it endwise to bring it intoproper position, and other mechanism for Specification of LettersPatent.

moving it bodily toward the spacer releasingescapements for the purposeof operating combina tions thereof.

The invention also consists in such a cylinder when made up of a.plurality of disks carrying appropriate and properly placed combinationsof said projections.

It also consists in certain novel constructions and combinations ofparts for render ing the )rimary invention more eilicient and practical.

In the drawing, Figure 1 is a rear elevation of the mechanism embodyingthe invention. Fig. 2 is a side elevation thereof. Fig. 3 is a sectionalside elevation in the plane indicated by line CC of Fig. 1; Fig. 4 is asectional side elevation of part of said mechanism in the planeindicated by line l)-D of Fig. 1. Fig. 5 is a plan view of the selectingcylinder and its operating mechanism. Fig. 6 is a transverse sectionalview of said cylinder showing one of the disks secured thereon andprovided with spacer operating projections, and also one of the spacingdisks. Fig. 7 is a side view of another one of the disks having theperipheral projections. Fig. 8 is -a magnified rear elevation of thepart of said selecting cylinder which is between the lines AA on Fig. 5.Figs. 9 and 10 taken together when the left end of Fig. 10 is placedagainst the right end of Fig. 9, constitute a diagrannnatic view of thedevelopment of the selecting cylinder. The right end of Fig. 10 is theright end of the cylinder when viewed from the rear of the machine. Fig.11 is a front view of the lower part of the spacer magazines, theirchannes and the upper ends of the tubes by which spacers released in theseveral magazines are to be conveyed to their point of use.

The spacers 3, which are to be selected and released by the mechanismconstituting the present invention, are to be stored in a plurality ofvertical channels 5, which are parts of the spacer magazines 4. Themagazines are to be like the magazines shown in sald prior applicationin that each has a contracted lower discharge mouth through whichspacers released from any channel in a magazine will fall into the tube6 associated with said magazine. In the prior application' thesemagazines are shown to be of various widths and they contain differentnumbers of spacer channels. The mechanism herein described, however, isintended for use in connection with magazines of the same size, each ofwhich magazines contalns seven spacer channels. The width of themagazines and the number of channels therein are matters whollyimmaterial to the present invention, although it is, of course, truethat in any specific embodiment of the in ven tion there must be acorrespondence between the size of the magazines and the number ofchannels therein, on the one hand, and the disposition of theprojections on the selecting member for selecting and operatingdillerent combinations of the escapemcnts of the magazine channels.

Associated with each channel is an escapement which may include a palletlever 98 having a weighted rearwardly projecting operating arm 99.Associated with each of these escapement levers, in operative positionand lying directly beneath it, is an operating lever 101 which ispivoted at its rear end to a fixed part of the machine frame. Each ofthese levers 101 normally occupies a substantially horizontal position.and they all extend over the selecting cylinder 100. And each of theselevers has, directly over the center of said cylinder, a downwardlyprojecting spur or pin 102.

All of the parts above mentioned, except one, viz., the cylinder 100,are in their construction, function and mode of operation substantiallylike corresponding parts shown and described in my pending applicatlonabovemcntioned.

The selecting cylinder has a shaft 10, which is rotativcly mounted intwo vertically movable boxes 11. These boxes are mounted, so as to bemovable vertically only, in vertical guide ways 12 formed in therearwardly projecting bracket arms 13 which are fixed to the frame 2 ofthe machine. Specifically these bracket arms are rigidly connected witha plate 14 which is rcmovuhly secured to said frame. The shaft 10 ismovable endwise in its hearings in these boxes, and the disposition toso move ondwise is unparted to it by a spring 15 which is seated in thetubular end of said shaft. A piston I6 is also fitted in this shaft, andthe spring acts to thrust this piston outward against a fixture. 1n theform shown, this fixture is the end of a tubular cap 17, which isscrewed into one of the side members of the machine frame 2. Thisshaftis restrained from moving endwise by the engagement of its oppositeend wltha vertical movable stepped wedge 91 which is secured to theupper end of a v rtically mov able rod 90. It is required that thiswedge shall move down a distance equal to the length of one of the stepsthereon every time a temporary spacer is introduced into a growing lineof matrices or type; but this wedge, its rod .10, and the mechanism formoving them may be precisely like corresponding part-s shown and fullydescribed in said prior application.

Attached to the shaft 10 is a pinion 18. A vertically movable rod 84carries at its upper end a rack bar '85 which engages with the pinion18, whereby, as the rack bar is moved up or down, said inion, andconsequently the shaft 10 and t 1e selecting cylinder 100 securedthereto, will be turned. This vertically movable rod 84 has its counterpart in the mechanism of said prior application, and the precisemechanism shown in that prior application may be. employed to move thisrod upward, whenever a matrix is added to the growing line, a distanceproportionate to the width of that addition. The rack bar is capable ofa slight upward movement independent of the bar 84.*this motion beingpossible because the lower end of said rack bar is seated in a socket 86in the upper end of bar 84. A spring 87 yieldingly holds said rack bardown in said socket. \Yhen the two bars 84 and 9C are moved by mechanismlike that shown in the said prior application or its equivalent, thecylinder will be moved to the left a definite step every time a tcln-.porary spacer is added to the line, and the cylinder will be turned,whenever a matrix or type is added to the. line, an angular distanceproportionate to the width of the matrix or type so added. The cylinderis made of such circumference, and its operating parts may be soconstructed that the cylinder will be caused to make a complete rev)lution by the addition, to the line, of matrices or type whose aggregatewidth is e ual to the number of units in the greatest lne shortage whichthe mechanism is adapted to justify.

A rocker in the form of a frame 20 is pivoted on a horizontal pivot atits rear end to the rear ends of the bracket arms 13. At the ends ofthis frame respectively are the forwardly projecting arms 21, each ofwhich carries a vertically adjustable screw,which screws severallyengage with the bottoms of the boxes 11. Near the middle of this framethere is an arm 23 which projects forward under the cylinder, and whosefront end rests upon a set screw 24, which is vertically adjustablethrough a fixed arm 25. The boxes 11, the shaft and the parts secured tosaid shaft are, therefore, supported by this frame, which is, in turn,prevented from yielding to the force of gravity by thtengagement of thearm 23 with the set screw 24. A vertical bar capable of being movedendwisc up and down is provided for swinging this frame upward andthereby lifting the selecting cylinder so as to cause it to operate theselected escapements. The mechanism for moving this bar 115 upward maybe sub-. stantially the same mechanism provided for that purpose whichis shown and fully described as the means for raising the correspondingbar 115 of said prior application. This bar in its upward movementengages with the arm 23, above described. It is, however, desirable thatthe upward movement of the bar 115 shall have no effect in lifting theselectiln cylinder until the cylinder has moved at. least one step tothe left. Therefore, the upper end 116 of the bar 115 is pivoted theretoand is therefore capable of being deflected into an inoperativeposition. A spring 117 which is stretched between a pin 118 on the bar115 and a finger 119 on the extension 116. tends to draw said extensioninto alinement with the bar 115, in which position it is operative. Thenit is in this position, the upward movement of said bar 115 will swingthe frame 20 upward as described; but when the extension 116 is swungout of this alincd position, for example, as shown in Figs. 2 and 3, theupper end of the extension is not beneath said arm 23. In the particularconstruction shown this is because the rear end of the arm 23 is offset. hen the extension 116 is alined with'bar 115, the upper end of theextension is beneath the straight part of this arm, but when the saidextension is drawn forward, as shown,-it is not beneath said arm, and,ifit be moved up. it simply moves up along side of the offset end of saidarm 23.

The extension 116 is held in its inactive position by a curved arm 31attached to a rock shaft mounted in suitable fixed bearings. Another arm32 is secured to this rock shaft and it normally rests upon a shoulder92 upon the bar 90 when said bar is in the position. as shown in Fig. 1,which it occupies before the cylinder 100 has begun its step by stepmovement to the left. Until that mo ement has begun, the extension 116is held out of range of the arm 23, but immediately the arm 90 makes itsfirst downward movemenr, so as to permit cylinder 100 to move endwise,the shoulder 92 is carried down away from the arm 32, and this permitsthe rock shaft 30 to be moved. Spring 117, by its action, then drawsextension 116 into alincment with bar 115, which is its active position,as above described.

Attached to shaft 10 is a ratchet wheel 8. A dog 41 is provided forengaging with this ratchet. This dog is attached to a rock shaft 40,which is mounted in the frame 20. A spring 42, tends to rock the shaftin the direction to carry the dog into engagement with the ratchetwheel. This movement of the dog, however, is normally prevented by theengagement of an arm 44 (which is attached to the rock shaft andprojects forward therefrom) with a )in 114 projecting from an offsetrigid upward extension 113 of the bar 115.

'hen the cylinder 100 has been turned and moved endwise so as to bringit to the proper position for selecting the proper number of spacers ofthe proper size, the bar 115 is to be moved upward. One of the firstresults of that movement is to release the arm 44 so as to pcnnit spring42 to swing the dog 41 into engagement with the ratchet 8. F urtherupward movement of bar 115 rocks frame 20 through arm 23, and therebythe boxes 11 and consequently shaft 10 and the parts attached theretoare raised. As they are raised the rack 85 by maintaining its engagementwith the pinion 1S acts to turn shaft 10 in the direction indicated bythe arrow on Fig. 4, and continues to so turn it until further movementis prevented by the engagement of one of the teeth of the ratchet withthe end of the dog '11. This brings the cylinder to a fairly accurateangular position, and corrects most slighterrors due to imperfectfitting of the teeth of the pinion and rack and some other minor causeswhich may be existent. The upward movement of the cylinder is continuedwith the result that it engages with the proper levers 101 associatedwith the proper number of magazine channels 5 containing spacers of theproper thickness for effecting the justification of the line. The rack85 offers no obstacle to the continued upward movementof said cylinder,because said rack being yieldingly connected with bar 84 may move upwith said cylinder the short distance which may be required. 'hen thebar 115 is again drawn downward and the bars 84 and 90 are caused toresume their initial positions, all of the described part return to thepositions in which they are shown in the drawings; the spring 86 be ingstrong enough to draw the rack bar down to the bottom of the socket 863.

There remains now to be described the particular construction of thecylinder. It is, broadly speaking, such a device as will be produced byrolling a selecting plate having the essential characteristics of theselecting plate shown in the prior application and patcuts, into thecylindrical form. Figs. 9 and 10 show a development of this cy inder.

The cylinder is divided lengthwise into six equal parts correspondingwith the number of spacer holding magazines and correspondingconsequently with the number of justifying spacers which may beintroduced into a line of matrices or type to justify the same. BelowFigs. 9 and 10 are brackets drawn to show the extent of these primarydivisions of the cylinder which are hereinafter termed magazinesections. The words first, second, third, fourth, fifth and sixth belowthese brackets will be used in order todistinguish one from another. Thefirst magazine section is that which is associated with the left handmagazine when viewed from the front of the machine, and with the tube 4associated therewith,this being the tube which is first moved forward soas to bring the temporary &

spacer attached to its lower end into the growing line.

contained in the associated channels. Each of these channel sections isagain sub-divided Each of these magazine sections, is divided into sevenequal parts correvisions are brought beneath the escapement operatinglevers. But since spacers are required from only the tirst and secondmagazines, these particular small sub-divisions of the channel divisionsoi the first two maga- 1 zine sections have pro ections 104, while 3those of the other magazines have not. The diff It is apparent thereforethat these escapement operating pro ections should be provided on ;onlythe right hand sub-divisions of the channel divisions of the sixthmagazine, in the two right hand sub-divisions in the filth magazine, andso on. show the width, in spacer nn1ts,of the spacers In making up thecylinder, disks 105 are jemployed, corresponding with the smallest intosix equal spaces, which correspond in width to the step by step endwisemovements of the cylinder controlled by the stepped wedge 91-. Thecylinder is divided circumthere are units of s aces in the lineshortage, which the describer mechanism is adapted to fill up, by theaddition of justifying spaces. T here are peripheral projections 104empirically placed in the various squares formed by these hypotheticallengthwise and circumferential sub-divisions. Some of these projectionsare circumferentially long, extending almost entirely around thecylinder. Some of them are short in the sense that they extendcircuniferentially only the distance of one square. The position andlength of these projections is indicated by the black blocking on Figs.9 and. 10. Some of these small lengthwise sub-divisions have noprojections at all in them. In fact. all of the channel divisionsassociated with the left hand magazine (viewed from the rear of themachine) have projections in only their rightend subdivision. Thechannel divisions associated with the next magazine have theseprojections only in two right hand sub-divisions; and so on, as shown.

It will be remembered that whenever a temporary spacer is added to thegrowin, line, the cylinder moves one ste to the left (as in Figs. 9 and10). This brings the left small sub-division of each channel divisionunder the associated escapement operating levers 101. But when thecylinder has made only one of said movements, only one permanent spaceris required: and that must be taken from one or the channels of theiirst magazine. Therefore, the left hand small subdivisions of thechannel divisions of the lirst magazine must be provided with suitablyplaced projcctions 104. But the left hand small sub-divisions of all ofthe channel divisions in the other magazine sections must not have anyof those projections 10-l, or otherwise spaces might be released fromsome magazine other than the first. \Vhen the cylinder has moved twosteps to the left, the next small sub-division of all the channeldilengthwise subdivisions of the cylinder, as described. On each ofthese disks are the required peripheral pro ection or projections 104corresponding in position and circum- 1 nel division.

ferential length with the requirements, as inferentially into as manyequal sections as dicatcd in Figs. 0 and 10. Each of these disks isprovided with a suitably disposed key-way 106 for en agement with a key107 which also lies in the longitudinal key way 108 in the shaft 10. Thekey ways in the disks are so placed that when the disks are placed uponthe shaft in engagement with the key all of the disks shall occupy therequired angular position relative to each other. There are 18 differentvarieties of disks required where there are one hundred and forty sevendisks required with spacer operating projections. The disks which arealike in respect to the number and relative position and size of theprojections are ditlerentiated from each other upon the cylinder bytheir angular posit-ion upon the shaft, as determined by the key way.Spacing disks 109 are interposed between the'disks having projections.These spacing disks are of various widthsas required.

There are many thin spacing disks,

namely, those which lie between two of the disks 105 which are placed inadjacent small sub-divisions of the same channel division. But, as willhe understood from the foregoing description explaining why in somechannel divisions six disks 105 are required, as in the channel sectionsof the first magazine, while in other channel divisions only one disk105 is required, as, for example, in the channel sections of the sixthmagazine, there is considerable space to be filled by spacing disks 109between the disks 105 of one channel division and the disks 105 ofanother chan- It is in order to fill these spaces and properly space thedisks 105 that the spacing disks 109 are made of various widths asshown. 'hen all of these disks are arranged upon the shaft they arecompacted together and prevented from endwise displacement hy hearing atone end against a shoulder 110 on the shaft and at the other end by anut 11] which screws onto said shaft. It is quite clear that this mannerof l l l l l making the selecting device very greatly re 117, theV-shaped edge of said disk by enduces the cost thereof, as compared withsuch a selecting plate, as is shown in my said prior patents andapplication, and as compared even with the cylinder in which theprojections are separately secured upon its periphery.

A cylinder having the peripheral projec -tions disposed and arranged asshown and described will correspond in function to the selecting plateof said prior application and patent. The ste by step lengthwisemovement of the cy 'nder will bring different small sub-divisionsthereof beneath the escapemcnt operating devices with which they areassociated. The turning of the cylinder brings different combinations ofsaid escapements beneath the dill'crent cscapement operating devices,just as the rearward movement of the selecting plate does in the priorconstruction referred to.

T he presentinvention is not at all depend ent upon the mechanismprovided for imparting to the bars 84, 90 and 115 their verticalmovements. They may, however, be moved, as before stated, by preciselythe same mechanism employed in the prior constructions referred to formoving corresponding vertical bars. The movement of the bars 8-1 and 90,however, control the movement of the cylinder circumferentially andlengthwise and bring it to the required position. The upward-.--movement of the bar 115 lifts the support for the cylinder, as beforedescribed, and causes peripheral projections thereon to engage with theescapcment operating devices 101 to impart the required movementthereto.Extreme accuracy in the positioning of this cylinder is required. Thedog 11 by its 006 )eration with the ratchet 18 comes very close toaccurately positioning the cylinder with respect to its angularposition, and the stepped wedge 91 comes very close to accuratelypositioning the cylinder with respect to endwise movement. It is,however, thought desirable that there should be certain additionaldevices i or insuring the accurate positioning of the cylinder. To thisend a toothed wheel 112 and a thin disk 113 are secured to the shaft 10.Above the toothed wheel and disk is a block 114 fixed to the frameworkof the machine having over the toothed wheel a downwardly projectingspur 116. This block also has six vertical kerfs or grooves 117 ada itedto receive the V-shaped edge of the dis When, therefore, the cylinder islifted, some interdcntal space in said toothed wheel embraces said spur116, and the disk 113 goes into one or the other of said grooves117,-and thereby, if required, the cylinder is turned or moved cndwisevery short distances, to bring it into an absolutely accurate position.If, when the cylinder is moved upward, the disk 113 is not squarely inline with one of the kerls l l l l l 1 l gaging with the sides of thekerf will tend to move the cylinder 21 very short distance endwise.Similarly the tooth. 116 will, by engaging with the sides of theinterdental space on the toothed wheel 112, cause the cylinder to turnin one direction or the other a very short distance, provided said tooth116 can not otherwise go squarely into said interdental space.
